We already know that Gwyneth Paltrow hated the Met Gala because it was super "un-fun." But perhaps another reason was that ex-BFF Madonna was giving her the cold, punk-clad shoulder the whole time.

Sources tell Us Weekly (via Radar Online) that the reigning queen of pop instead conversed with Beyonce, with whom Gwynnie's forged tight bonds, during the event.

Paltrow and Madge had a major falling out last year, when Gwyn abruptly cut ties with Madonna in favor of Cameron Diaz. (Maybe Madonna just wouldn't hold Goopy's hand during bikini waxes.)

But the mean girl power-plays are still going strong, as evidenced by Madonna's icy treatment at the Met Ball.

“[Madonna] chatted with Beyonce for most of the evening and didn’t even glance at Gwyneth," said a source. "Everyone talked about it."

Previously, when the spat began, a Paltrow confidant told the mag that Gwynnie bailed on the friendship after Madonna "sh-t on her, over and over.” Now, Madge is gunning for vengeance: “She feels Gwyneth abandoned her [and] will do anything to make her suffer.”

Picture Gwyneth Paltrow fighting off an army of thousands of Colombian boys under Madonna's command. (There's your Pepper Potts 'Iron Man' spin-off, Hollywood. You're welcome.)
